This invention relates in general to containers suitable for packagingand dispensing milk and otherA liquids, and, more particularly to sealedcontainers ci the type provided with collapsible, hidden spouts arrangedto .be exposed by opening of such containers.

The primary object of the invention is the provision of a container ofthe type referred to above, shaped from a single blank of inexpensive,ioldable, moisture-proof material, the container including' integrallyformed therewith a co1- lapsible, spout-like closing and dischargeportion which in collapsed condition forms a sealing element and inopened up condition provides a discharge element.

Another object of the invention is the provision of a container shapedfrom a single blank of inexpensive, foldable, moisture-proof material,the container being closed at its top vby a staple member, and includingintegrally formed therewith a collapsible, spout-like closing anddischarge portion having its tip end folded inwardly, the closing anddischarge portion in collapsed condition forming .a sealing elementreadily and easily exposed, and shaped to a discharge spout by tearingpart of the top of the container on predetermined tearing lines withoutthe necessity of removing the staple from such top.

The above and other objects of novelty of the invention will be eitherspecifically pointed out or will become apparent when referring, for abetter understanding of my invention, to the following descripton takenin conjunction with the accompanying drawings, wherein:

Fig. 1 is a perspective view of completely sealed container constructedin accordance with the invention;

Fig. 2 is a fragmentary perspective view of the container shown in Fig.l, the container being partly torn at its top edge, showing thecollapsible, spout-like closing and discharge portion exposed and partlyopened up;

Fig. 3 is a fragmentary perspective View similar to Fig. 2 showing thecollapsible, spout-like closing and discharge portion fully exposed andopened up;

Fig. 4 is a fragmentary perspective view oi the completely sealedcontainer with parts broken away to disclose the sealing and closingportion of the collapsed, spout-like closing and discharge portion cithe container; and

Fig. 5 is a plan view of the cut and scored blank prior to its foldinginto a container.

Referring now more specifically to the structure of the inventiondisclosed in the drawings,

2 reference numeral 2 denotes a container formed with a slanting top orclosing end 3. This container is folded from a pre-shaped, 4scored blank4, (see Fig. 5) of suitable foldable, moistureproof material, whichblank is composed of four panels y5,13, 1 and S 'separated by verticalscored vlines 9, Hl and lll dening folding lines and facilitatinglcreasing ci the blank. Adjoining to panel '8 vand separated therefromby a score line l2 is a sealing Vilap ill which is to receive `'anafdhesive for attaching it to the inner face of the adjacent free edgeof panel 5 when the container is folded 'to shape. The lower ends of thepanels are dened by a horizontal score line 'I5 forming a hinge linevfor the bottom naps I8, l1 and I8 of the container which iiaps form itsbottom end 'and by overlaying provide -a bcttornoi -dcuble thicknessinsuring a strong and rugged structure. The upper horizontal score yline19 also fori-ns Va hinge line and separates the side panels 5, 6, l and8 from top sealing flaps 2|, 22, 23 and'lll which are horizontallyscored by score line 29 for a purpose later to be described. Sealingnaps 2| and 23 are identical in construction, each including a secondarysealing flap section i125, 12B respectively, formed by scoring the flapson lines 21, 28 respectively, which score lines are partly perforated asindicated at 29 and 33. The sealing naps 22 and 24 are of identicalconstruction with the exceptionl that sealing flap 122 additionallyincludes an extension 3i to be used for a purpose later to be described.

Sealing flap 2d is scored on diagonal lines 32., 3-3 which runsymmetrically at an inclination from the lower corners 34, 35 of theflap to a point 36 on score line 2i) and thence into a single verticalline 31 ending at the upper edge 38 of such flap. In closed, sealedcondition of the container, top sealing naps 22 and 24 extended upwardlyfrom side panels 5 and 8 are tucked under the top sealing ilaps 2| and23. This is effected by folding the flaps 22 and 24 on score lines 32,33 and 31 and 32', 33 and 31 until adjoining portions of the score line20 contact each other, folding of one of the two secondary sealing flapsections 25, 26 over the top edges of the vertically extended portions39, 40, il and 42 of the respective top sealing ilaps and the other oneof said secondary sealing flap sections, and rigidly connecting thesealing flap sections in their closed position by a staple 43 which isextended through secondary sealing iiap sections 25, 26 and thevertically extended portions 39, il and 42.

Sealing flap section 40 is not penetrated by` staple 43 so 'as to permitpulling out of the flap section 22 to act as a dispensing spout. Forsuch purpose sealing flap 22 has the score lines 32',

33 'and 31'-which :are the equivalent of score lines 32, 3'3 and 31 onsealing ap section 24- extended on straight lines ,beyond their meetingpoint 36 to the top edge 44 of ap 22 and has portion 45 arranged betweenthe extended score lines 32 and 33 folded outwardly to prevent grippingofV said portion 45. Y

Containers of the type described have a uidtightly sealed top portionincluding a collapsible,

spout-like closing :and discharge flap portion v22 which for dispensingpurposes can readily beV Vclaim is:

pulled vout and openly exposed without removing j staple 43 aft-ersecondary sealing flapsections and 26 are partly torn from sealing fla-psections 2| and 23 on perforated lines 29 and 39,.A to permit 1suchpulling out of the collapsible, spout-like closing and discharge flapportion` 22,

all as clearly indicated in Figs. 2 and 3.

However, outward folding of the portion 45 of top sealing flap 22effects lowering of the top Vedge of this portion and such lowering ofthe top edge of portion 45 Ymay `cause leakage of the sealed containerin -thisV area of such portion. Such a danger of leakage at this pointis overcome by providing flap 22 with the extensionV 3l previouslyreferred to. This extension which is an integral part of iia-p ZZ'an-dextends'fromY the middle portion of its top edge 44, forms a'col- Y 0lapsible secondary spout section on the portion 45 of nap 22. For suchpurpose extension 3i is separated from portion 45`by a score line 45.Furthermore, score line 3l `continues through extensionV 3l as scoreline 4l, and finally extension 31 is additionally scored by two inclinedscore vlines 48 and 49 which extend from the intersectand easily besufliciently 'opened for discharge of their contents without removal ofthe staples holding the container in sealed condition by partly tearingsecondary sealing nap sections 25 and 26 from top sealing flaps 2| and23 on per- A1;' A liquid container of foldable, moistureproof materiallcomprising four side-walls scored at their upper ends -to provide aclosure embodying a pair of1 outer sealing members and a pair of innersealing members arranged between "'said outer 'sealing 'members andco-Operating therewith, said inner sealing members each being inwardlyfolded onsymmetrically arranged, inclined fold lines intersecting eachother and a horizontally arranged fold line extended through the pointof intersection of said inclined fold lines to form each vinner sealingmember with asingle, inwardly and upwardly extended, triangularly shapedportion, Vone of the inner sealing members having its inclined foldlines extended beyond the point of intersection to the to-p edge of suchsealing member and the area of such sealing lmember between the extendedportions of the inclined fold lines folded outwardly to form said innersealing member with an outwardly extended collapsible spout-likedischarge element extended above the triangularly shaped side -portionof said inner sealing member. Y

2. A liquid container as `described in claim 1, wherein the said oneinner sealing member includes at its top edge an extension opposite thearea enclosed by the extended portions of said inclined foldV lines,wherein said extension is formed with fold lines arranged parallel tothe said inclined fold lines, and wherein said extension is folded onits fold lines to decrease the size of the top opening of the collapsedspoutlike discharge element and facilitate sealing of inch dischargeelement when in collapsed posiion. i Y
